Does 'gamblegate' mean the Conservatives are a busted flush for voters?

In any election campaign, a lot of attention shifts to undecided voters. As this campaign moves into its final week, Niall Paterson looks at how the election date betting scandal is cutting through to those who are still wondering who to support - and those who could change their mind.  

He speaks to political correspondent Darren McCaffrey who has spent the campaign covering the Conservatives and to pollster Luke Tryl, from More In Common UK, about how this scandal has compared to other moments of the election.
